The CSAF was conducted online via the SSRS Probability Panel among adults age 18 and older who participated via the web on PC, laptop, tablet or mobile phone. It included 1,207 participants and data collection was conducted from June 28 to July 7, 2017. The SSRS Panel members are recruited randomly from a dual-frame random digit dial (RDD) sample, through the SSRS Omnibus Survey. The SSRS Omnibus survey is a national (50-state), bilingual telephone survey. The sample used for the Chapman University Survey of American Fears mirrors the demographic characteristics of the U.S. Census. For additional methodological details, see the full report.
